Worth every dime !!!! By Joeon 3/17/2015

This valve is amazing. A bit pricey, but soo worth it. Just make sure you have quick disconnect fittings and a gate valve above just in case you need to clean it.

Worth the extra money!By Eric Ranschauon 2/13/2015

When I set up my 75 gallon tank the first time, I added a swing type check valve (http://www.bulkreefsupply.com/swing-check-valve-1-bcc097feafe80f489ef54b0720ca059c.html) to the return line. It lasted about eight months before it had gummed up sufficiently that it would no longer prevent back siphons when I turned off the return pump. Needless to say, they're very difficult to clean.

Replaced it last night with a Wye check valve and I couldn't be happier! It comes apart so I'll be able to clean it when it gets dirty, and I swear I'm getting twice the flow from my return line due to the more efficient design of the check valve itself.

Awesome check valveBy Eon 2/10/2015

This is the best check valve I have ever used. Much better than swing style valves. The build quality is solid - if you order one; you will understand the price when it is in your hands.

Only Check you should buyBy AJSon 11/25/2014

I have installed multiple versions of check valves, and this one is by far the best. I would suggest using unions for easy removal, and mounting in the proper manner to avoid and problems like I have read in other reviews.

Pretty Impressive so farBy AVon 9/27/2014

The quality of this product justifies the cost and I installed in my basin about a week ago. I'll have to inspect it in a month or two to stating that it's still functioning properly. Based on other reviews it is getting stuck in the open position after getting some debris or dirt in the check valve. One note, when it states 3/4 check valve, they are referring to the actual check valve itself, not the size pipe or hose you are connecting it to. That measurement OD is1", so I had to modify to allow it to work with my project.

Great valveBy Danielon 3/26/2014

There are tons of valves available, but the bottom line is if you can afford this one then buy it!!! If a piece of mind is what you are looking for this is the valve for you.

Have to keep it clean in order for it to work.By LTon 2/25/2014

I've had this about a year. Have to keep it clean in order for it to work. the piston valve gets stuck in the open position about 4 months after a cleaning.

I thought it was overpriced when ordering but was impressed to see how solid and well built it was. Works well and easy to maintain. Well worth the money for the peace of mind.

Failed to PerfomBy Christopheron 2/3/2014

Christopher wouldn't recommend this product to a friend

This check valve failed to perform during a power outage. I use it to stop the water from back-flowing from my display tank into my sump. The power went out one night and the check valve failed to close (this was within two weeks of purchase so it was still new/clean). This worked when I turned the power off to the pump, but failed in a real world power outage. I wish I could get my 50 dollars back, this was a complete waste of money and could have been a disaster if my sump wasn't big enough to contain all the back-flow.

The check valve is working as intended and feels like it was made strong and to last. I highly recommend to anyone with an in sump skimmer or anyone with a small sump. Enjoy!!

I was skeptical when setting up my first sump but after buying this, I don't worry about my sump overflowing. Very heavy duty build. Haven't had an issue with it. It's a bit pricey but the peace of mind it provides makes it worth every penny.

After purchasing this item i felt that i spent too much money on a check valve. When i received it and installing it I was more then pleased with my purchase. I could easily clean it unlike my old flapper check valves i have on my older tanks. I will soon purchase more to replace the older ones.

Very NiceBy MICHAELOon 9/30/2013

This is a well built back flow check valve. A little pricey, but considering what it will help you not have (i.e flood) it pays for itself. If you want a guaranteed check valve that you can physically take out ,clean and inspect. This ones for you!

It’s the best check valve on the market. I switched from a different brand. George Fisher check valve is more expensive but worth it.

Good materials, but does not reliableBy Kevinon 7/6/2012

Kevin wouldn't recommend this product to a friend

I was very impressed with this check valve out of the box, but it fails to close 1 out of 10 times during my feed cycle. I have two of these plumbed into two different returns, and both exhibit the same behavior. The units have been used for less than 3-4 weeks, so they are not dirty. I am disappointed in the performance given the high cost.

Simple and functionalBy Kyleon 5/19/2012

I purchased this check valve because I was skeptical of the cheaper flapper-style ones. Replacing plumbing is not something that I enjoy doing, so I wanted to get a quality valve that would last. This valve works exactly as it's designed to and is very easy to disassemble and clean. One thing to think about though is the pump that you plan on using with this valve. I have a Tunze Silence 1073.05 that is variable speed and I found that I needed to have it nearly cranked to the max to provide enough pressure to raise the valve. This is fine because I run my return pump wide open anyway, but if you have a less powerful pump, you might find that it isn't powerful enough to open the valve. Overall, a great product worth the price and I would certainly recommend it if you're looking for a check valve.

works great and is very well made, spend the extra dollars!

great valve, but call for sizingBy Hugoon 3/17/2012

Hugo would recommend this product to a friend

i have .75" flexible tubing in my sump, and figured this would fit. The slip ends themselves are actually 1" and 1/16" inches, my .75" tubing wont fit. The valve: Inner diameter is .75", outer slip fit diameter 1.0625 (1" and 1/16"), end to end is 6.25" and at the widest part it is 3.375" (3" and 3/8"). Great looking valve, great build quality, I hope my review saves some people an unexpected trip to the plumbing store.

Quality is worth the priceBy Thomason 3/13/2012

My initial return had a swing check valve. when the pump turned off a huge water hammer developed that would take several minutes to resolve. I replaced the swing check with this valve and no more water hammers. The design and quality is so much better than a swing check.
